ABSTRACT:
A device for detecting the actual position of an elevator car using a computer has an interfloor detector 5 which detects the elevator car passing through an intermediate zone between adjacent landing floors, and a floor level detector 6 which detects when the elevator car is located at a landing floor. A position detecting device which is fed output signals from the two detectors precisely memorizes the actual position of the elevator car.
